My grandfather was a steam engine driver, believe it or not. I have an image of him from when I was six year old, coming down through this cloud of steam like a god. That's stayed with me all my life.

My favourite form of public transport? The subway. I live in New York, so I use it sometimes.

Jaume Collet-Serra [The Commuter director] and I are like dance partners. I wouldn't quite say we're like Astaire and Rogers, but we clicked the first time we worked together eight years ago. We've worked together on four films now. You really get to know each other.

I keep pretty fit in life. You have to. Particularly when it comes to preparing for action films.

Don't bottle stuff up. It becomes like acid.

I'm reading a lot of Nordic noir at the minute. Henning Menkell. He's a wonderful author and he just passed away last year. He wrote Wallander, these police detective books. I would highly recommend those.

If I wasn't an actor I would drive a forklift truck. I think I could still drive one now. I did that for 18 months back in Ireland in a Guinness factory. Yeah, I think I could still manage that.

My best relationship advice is if you've got anything on your chest, get it off it. Don't bottle stuff up. That would be my advice for any relationship: family or marriage. Don't bottle stuff like that because it becomes a cancer. It becomes like acid and it's best to get it out. It's healthier that way.

The best advice I was ever given was from an actor, who is no longer with us, called Colin Blakely. He was one of Laurence Olivier's founding players in the first National Theatre company with Maggie Smith and Robert Stephens. I loved Colin Blakely. I did a little TV play called Nailed with him many years ago in 1981, and he said to me: "don't stay relaxed, the next stage of relaxed is falling asleep. Stay poised." And that's stayed with me. Be poised and ready for anything.

The years go too fast. When I think of the decades, it makes me feel like Gandalf or something. Ancient. My thirties weren't bad. My forties were even better. I'm in my sixties now so yeah - the sixties are OK, but the forties I liked the best.

Judi Dench planted a tree in her garden for my late wife Natasha Richardson. I didn't know that before and I’m thankful to know now. I haven't been. I would love to go there. That's lovely. That's a great thing.
